Bootcamp booting clobbered by Yosemite upgrade
I've enjoyed being able to boot into OSX Mavericks or Windows 8.1 for the past year on my MBP (mid 2012, single 500GB SSD) but I recently performed the Yosemite upgrade. The resulting OSX installation appears to work fine but when I hold down the Option key after the chime the option to boot from Bootcamp Windows is missing. Worse, when I set "Startup Disk" to Bootcamp Windows the result fails.
@Loner T usually requests the following Terminal results so here they are:

I would appreciate help getting Bootcamp booting again.
